Component Testing
Windshield Wiper Washer Switch
- With the wiper switch in the HIGH position, test for less than 2 ohms of resistance between the ground terminal D and the signal terminal C.
- If greater than the specified range, replace the windshield wiper washer switch.
- While cycling the wiper switch through each delay and speed position, test for the specified resistance between the ground terminal D and the signal terminal E.NOTE: If the switch tests open in any switch position other than Off, test the signal circuits for a short to voltage before replacing the switch.
